I have a WR450F 2007 with an alloy frame. I use it for Enduro racing in the UK. The front forks have leaked a few times, but with a clean up they do not leak. I decided to take the forks out, unscrew the caps, slide the outer part all the way down and drain the oil out. I then refilled the outer tubes with fresh oil about one and a half inches from the top of the outer tube, slid the outer tube back up and screwed back together. I used 550ml of oil in each fork.
Can someone advise if I have done wrong or right please.
